Latex

Org mode is well known for its powerful taking notes and task management capabilities, but for me it is always (or at least now) the document preparation mechanism that truly attracts me. Just imagine how amazing that we can just write content in org mode and then convert it to either PDF through LaTeX or HTML. Actually since Org mode is so good at these LaTeX tasks, I am even using the Org Beamer rather than the original LaTeX Beamer to prepare presentations.
